An awk clone targeting the JVM. Can be found on its SourceForge home page. Very feature-complete and very compatible with most of the awk family. (Occasional minor changes to source might be required to get it to run.) It features a powerful extension system that gives it access to the overwhelmingly large set of Java libraries if desired (all on an explicit opt-in basis) and it also features the ability to compile to JVM bytecode to make awk scripts, in principle, usable as components in a broader Java/JVM-based system.
